SKYLIGHT.

Application filed June 3,

This invention relates to a certain new and useful improvement in skylights. It has for its principal objects the provision of a ventilating skylight which may be controlled and operated, at will, from a position below; to provide for the automatic opening of-the skylight when the temperature in the building raises to a certain degree; to produce a simple and compact structure which takes up only a minimum space upon the roof of the building; and to attain certain advantages as will hereinafter more fully appear. 7 i

The invention resides in the novel features of form, construction, arrangement, and combination of parts hereinafter described and pointed out with particularity in the appended claims. I

In the accompanying drawing, which illustrates a practical adaptation and embodiment of my invention, 7

Figure 1 is a view of the complete sky light, partly in end elevation and partly in transverse vertical section;

Figure Qis an enlarged fragmentary trans verse vertical section of the skylight, taken through or about the middle of one of the ventilating openings and. the closure therefor and Figure 3 is a fragmentary horizontal section at the corner portion of the skylight.

Referring more in detail and by reference characters to the drawings, 1 designates the rectangular base of the skylight, which, as shown, comprises preferably a brick curbing, 7 although it is obvious that this base may be of any other suitable formation and material.

Extending around the'outer edge portion of and suitably fixed to curbing 1, is an anchor-member 2, preferably in the form of an angle, as shown. Secured to the anchor-1nemher 2, is the lower horizontal frame-member 3 of the skylight base structure, preferably of angle section, as shown. The frame-member V 3 has corner and intermediate uprights or posts 4, preferably angle bars, as shown, secured thereto and to which the respective mullions 5 and 6 are attached.

The corner mullions 5 are in the form of box-like, sheet metal construction, substan tially L-shape in cross-section, with rabbetted marginal portions 7, and having outwardly presented iianpjes at the base of said portions, as best seen in Figure 3, and co-operating with said flanges and portion in the formation of channels or slideways for the respective ver- 1925. Serial no; 34,623.

tically slidable doors or closures 9" for the ventilating openings to' be presently described, are angle-members-8.

The intermediate mullions 6 are also of box-like, sheet metal construction, substantially T-shape in transverse horizontal; sec tion, with rabbetted portions 10 and-outward- :ly presented flanges at the base of said'p'ortions, as also best seen in Figure 3-,with which angle members'll col-operate to provide' opposite slicleways for the doors or closures 9'. i The respective mullions 5 and- 6 extend down for a considerable distance below the upper edge of the curbing 1, as shown, preferably substantially to the bottom of" the curbing, theheighth of which latter is preferably approximately one-halffl the overall heighthof the side walls ofthe skylight structure.

At the upper ends of theuprights 4', are horizontal angle member's 12,011 which a fixed top 13 is mounted; This top, as shown, is preferably of the hip-roof type and comprises a plurality of metal'franre members 14 on and between which glass panels 15 are suitably secured.

The doors or closures 9, which are slidable vertically on and between-the respective mullions 5 and 6, comprise hollow sheet metal boxes having marginal flanges 16 loosely fit ting in the guide-slots 'in the mullions, the 7 doors or closures 9 being preferably provided on their vertical edge-portions with antifriction rollers 17 whichnbear upon the opposed faces of the mullions.

Extending around the skylight, ust below the top 13, is an overhanging eaves molding or water-shed 18 comprising an inclined sheltering portion having a depending substa ntially vertical flange 19 at its outer edge, and on the lower-edge ofwhich latter is an outwardly extending and downwardly in-' clined lip or deflecting flange 20; and to further make the structure weather-tight,

filler plates or liners 21 are inserted between the respective uprights 4L and the mullionso and 6. I

The upper portion of the structure may be suitably braced, preferably by tie-rods 22,

shown, connecting the upper angle members 12. So, too, the lower end portions of the mullions 5 and 6 may be tied by anglemembers 23, which latter, in addition'to bracing the mullions, serve as stops for respective 24 fastened to bracket extensions 25 on the inner faces of the doors or closures and passing over pulleys 26 secured ,to the angle members 12. At a suitable place within the length of each cord 24, is a fusible link 27.

this arrangement, a theatre or other building may be readily ventilated, as it is only necessary to loosen the cords or cables 24 to permit the doors or closures 9 to drop by gravity and thus uncover the openings, the degree to which the openings are uncovered bemgfull or partial and under the control of the operator from the floor or other convenient position in they building below the skylight. In case of fire or heating of the building above a certain degree, the fusible links 27 will melt and separate the upper portions of the cords or cables 24:, whereupon the 7 doors or closures will drop automatically by gravity.

It is thus obvious that a structure is pro:

l duced which meets with the requirements of fire department and insurance regulations,

and, doors or closures 9 being vertically slidable, there are, no projections or obstructions tointerfere with the work of firemen upon the roof when the doors or closures are opened. i

I am aware that changes in the form, construction, arrangement, and combination of the several parts of my new skylight may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is: V

1. In a sk light, a base curbing having an anchor mem er thereon, a frame comprisin a horizontal angle member secured to said anchor member, uprights comprising angle members secured to said horizontal member,

a second horizontal angle member secured to the upper end portions of said upright angle members, a fixed top mounted on said second mentioned horizontal an le member, said top comprising a multiplicity of frame members having glass panels secured thereon and therebetween, a series of box-like sheet metal mullions secured to'sa-id upright angle members, said mullions having slidewaysin their opposed sides, a series of box-like sheet metal closures having marginal flanges working in the slideways of said mullions, and cords secured to said closures and being passed over pulleys on said frame and down to a place below the skylight for operating and holding said closures.

2. In a ventilating skylight, a mullion of box-like structure having opposed rabbetted marginal portions and outwardly presented flanges at the base of said portions, and angle-members fixed to the flanges and co-op1erating with said marginal portions in the formation of'closure slide-wa s.

In testimony whereof, have signed name to this specification.
